Hi,
Please, note that WPNewsman only sends confirmation and welcome emails to new subscribers during the subscription process.
After the subscribers are added to the list as “confirmed”, WPNewsman does not automatically generate or send any emails to the subscribers. It can only send emails after you manually press the “Send” button.
From your message I understood that you imported a list of 240,000 emails in WPNewsman and sent an email to the list. As a result your site was blocked. It’s not the fault of WPNewsman. It just did what you told it to do.
If your hosting plan does not allow you to send so many emails at a time, ask your hosting company about sending restrictions and set email throttling in WPNewsman settings.
If your site was blocked because you had a high bounce rate or spam complaint rate, consider verify your list and remove invalid emails from it. Then re-import good emails and send a re-subscription request to those people.
I didn’t imported a list of 240,000 emails,
but the plugin has generated a long tail of automatic and random messages (about 240000) and it cause a spam warning from my hosting.
I disable it and the spam message was stopped.
I found a lot of files of a malware in upload folder.
I need to set the permission of upload folder to 755, as suggest from WordPress site support, but the plugin require it writable.
Wich code of permission folder i have to set to preserve it from spam attack?
